Yes, I think the way it appears theatrically makes more sense, in terms of how it’s flipped. However, that’s just a still image mockup, I didn’t test it in motion.
I will say Boba’s placement in the theatrical shot makes it feel odd. In the original shot Boba is pointing his gun toward the side of the frame with less space, which is odd from a framing standpoint. I think in either case, flipped or unflipped, he would need to be reframed like he is in my mockup to point the gun toward the area of the frame with more space.
